The Offer

Book a 30-minute scoping call.

A structured call to determine whether the engagement is worth scoping — not a sales demo, not a free consulting hour. You leave with a written read on whether to proceed; I leave with enough context to quote against.

No deck. No slides. No discovery questionnaire sent in advance.

What the call is

Thirty minutes, structured. Not a pitch.

01 — Agenda

You describe the surface, the constraint, and the metric you'd move. I describe the engagement shape, the team I'd assemble from the bench, and the first two weeks of work.

02 — Who should attend

One decision-maker. The Head of Product, a founding designer, or the founder themselves. Pulling in a committee signals the engagement isn't real yet — we can wait.

03 — Deliverable

A short written scope within two business days of the call: deliverables, timeline, fixed fee, and the single UX metric guaranteed in the SOW (activation, retention, or task-completion time).

04 — What it isn't

Not a free consulting hour. Not a portfolio walk-through. If the work isn't a fit, you'll be told in the first five minutes and the rest of the slot is yours.

Objections, answered

Four questions a skeptical buyer asks first.

What does a typical engagement cost?

A first-engagement scope lands between $48K and $140K USD, fixed-fee, billed in two milestones against the SOW. Engagements run 3–8 weeks. Second-engagement scopes, once the metric is established, are quoted separately and usually run shorter.

Will I be talking to you, or to an account manager?

To me. There is no account manager, no producer, no project coordinator between you and the work. The person on the scoping call ships the code. The person answering Slack is the person writing the components.

What happens if the scope grows mid-engagement?

The original SOW is treated as a contract — additions are quoted as a change order against the same metric. No silent scope-creep, no hourly billing. Roughly one in four engagements grows in the second half; the conversation about it is in writing, not a phone call.

Is the call a sales pitch?

No. If the work isn't a fit for this practice, you'll be told in the first five minutes and pointed at a designer who is. About 30% of scoping calls end without an engagement, usually because the team isn't far enough along, the metric isn't yet measurable, or the timeline is shorter than three weeks.

Book the call. The next thirty minutes decide whether the next six weeks are worth scoping.
